This invention relates to the apparatus for ex tracting water from a wet textile and then drying the same.

The object of the invention is the production of apparatus with which a wet textile and the like is subjected to a suction effect to extract the water therefrom, and subsequently dried by forcing heated fresh air therethrough.

The second object of the invention is the production of apparatus, whereby a plurality of Wet textiles and the like, one after the other and continuously, first have the water therein extracted and then subsequently dried.

A suction tank is designated in its entirety by the numeral 29, and comprises the cylindrical shell 2|, the top wall 22 and the bottom wall 23. A pair of screens 24 and 25 extend across the interior of the tank 20. To the outer face of the top wall 22 is secured the conical shaped support 29, having the bottom flanges 30, through which extends the inlet conduit 3| and which has its upper end fastened to said support 29. The said conduit 3| extends through the screens 24 and 25 and has extending therefrom the valve rod support 32. From the inner face of the shell 2! extend the journal bracket 33 and the guide bracket 34. A lever 35 has its upper end pivoted to the journal bracket 33 and to its lower end is fastened the ball float 36. The lever 35 with itsball float 36 functions as a trap. A locking lever 38 is pivoted to the conduit 3| by means of the pivot 39 and has formed therewith the latch end 49. A vertical lever 4| has its lower end pivoted to the lever 35,. by means of the pivot 42 and its upper end is pivoted to the locking lever 38, by means of the pivot 43. From the lower portion of the suction tank 20 extends the overflow piping 49 and to the latter is connected the spring controlled check valve 50.

Through the upper end of the shell 2| extends th T shaped valve chamber 52 which leads into the suction tank 20, having the valve seats 53 and 54 at its opposite ends. A conduit 55 having the flange collar 56 at its end extends from the valve chamber 52. A T shaped inlet fitting 58 is indicated with the open end 59, which is connected to the valve chamber 52, and at the opposite end of the fitting 58 is shown the end wall 5 60. An inlet conduit 6! extends from the inlet fitting 58.

A valve rod is designated in its entirety by the numeral 65, and at one end thereof has the latch cavity 63, and its other end is threaded for the 10 cap 57 and the locking nut 68. The valve rod extends through the valve chamber 52, the inlet fitting 58 and the support 32. Valves l3 and 14 are fastened to the valve rod 65 and respectively actuate with the valve seats 53 and 54. A hel- 15 ical spring 15 encircles the valve rod 65 and its ends bear between the wall 50 and the cap 61.

A blower is designated in its entirety by the numerallB, and is shown with the flange collar 19 at its inlet end, which is connected to the 20 flange collar 55-. The outlet conduit of the blower is shown at with the flange collar 8|. An outlet fitting 82 is interposed between the conduit 80 and the blower 18. A heating coil 85 for steam is positioned in the casing of the blower l8 and is 25 indicated with the inlet piping 86 and the outlet piping 81.

An electric motor 90 has its armature shaft connected to the shaft of the propeller of the blower 78, by means of the coupling 9|.

A drying tank is designated in its entirety by the numeral 95. The said drying tank comprises the cylindrical shell 96, having the flange 91 at its upper open end for the detachable cover 91a. The bottom wall for the tank 95' is 35 shown at 98 having the opening 99 and an outlet sleeve lflll extends from the lower end of said tank 95. The flange collar 8| is connected to the Wall 98.

Upon the wall 98 is supported the hollow py- 40 ramidal shaped support I05, having the bottom flange I06 and the outlet openings )1.

A rod H!) has its lower end connected to the support and its upper end is threaded as shown at HI. A cap ll2a is in threaded en- 45 gagement with the threaded end III of the rod Referring to Fig. 1 a spool shaped material carrier is designated in its entirety by the numeral H5. The said carrier comprises the bar- 50 rel H6, having the perforations Ill and the flanges H8 at its ends. To the flanges H8 are fastened the flanges I20. The carrier H5 has wound around its barrel N6 the textile I22.

The carrier H5 is positioned upon the suction tank 20, with one of its flanges H8 hearing on the bottom flange 30 of the support 29. Upon the flange H8 at the top end of the carrier H5 is' positioned the cap II 2 similar to the cap II2a already described.

Referring to Fig. 2 a second spool shaped. material carrier similar to. I I5 is designated in its entirety by the numeral 50., and is indicated with its barrel Eifia, having the perforations IIIa and the flanges Ba and I29a. The textile I22a is wound around the carrier The carrier II5a is clamped in position by screwing the cover II2a to the upper end of the rod H9.

To operate the fluid extractor and drier, the carrier H5, having the wet textile I22 wound around its barrel H5, is positioned upon the suction tank 29, as shown in Fig. 1. The -valve rod 55 is moved in the direction of the arrow A, Fig. 3, against the tension of the spring I5, until the latch cavity 66 is locked with the latch end 49 of the locking lever 38. In this position of the valve rod 65, the valve I3 is raised from its seat 53 and the valve 74 is seated on its seat 54. The blower 'l8 is now turned by the electric motor 9D and air is sucked through the textile I22 as indicated by the arrows B, Fig. 1, and flows through the perforations II! of the barrel I I6. As the air flows through the textile I22 globules of water from the moisture of said wet textile I22 is carried therewith. The mixture of the air and the globules of water drops through the conduit 35, as shown by the arrow C, into the suction tank 26. The air in the mixture, by 1 virtue of the increased diameter of the tank 29 over the diameter of the conduit 3|, separates from the gobules of water, which drop to the bottom of. the tank 20. The air rises and flows through the screens 25 and 24, which also function to separate the air from the water globules. The air is drawn through the valve chamber 52 and flows through the conduit 55 while it is pulled into and forced through the blower I8. It is evident that by the steps already described, practically all of the water is extracted from the textile I22- The air as it flows through the blower I8 is heated by the heating coil 85 and is forced through the textile I22a, in the drying tank 95. In the latter a carrier 5:1 with its textile I22a is positioned, which has previously had its water extracted in the suction tank 20. When the water has been extracted from the textile I22 the water level in the suction tank 29 has risen sufiiciently'to raise the ball float 36 to a height, whereby the latch end 40 is automatically unlocked from the latch cavity 66 and the tension of the spring I5 moves the valve rod 65 in the direction of the arrow G, Fig. 5. By this means the valve I3 is seated on its seat and the valve I4 is raised from its seat. In this position of the valves I3 and I4 no further suction effect is produced in the suction tank 20. When the water in the said tank 20 has risen to a predetermined level it is discharged therefrom through the spring controlled check valve 59.

When the valve I3 is closed and the valve I4 is open, atmospheric air is pulled through the inlet conduit 6|, in the direction of the arrow H, Fig. 3, and is sucked through and discharged from the blower I8 and directed against the textile I220. in the drying tank 95. The air is heated by the heating coil 85 before it enters the the drying tank 95, and another carrier with its textile that has had its water extracted by means of the suction tank 20 and its appurtenances is positioned in the drying tank 95.

At the same time another textile with its car- 5 rier is placed in position on the tank 20 to have its water extracted by the suction tank 28 and its appurtenances.

The foregoing steps are repeated for a plurality of textiles one after the other, that are to have the water therein extracted and then dried.

Referring to Fig. 6, the invention is modified by eliminating the drying tank 95.

In this modification the outlet conduit of the blower is again shown at with its flange collar 8|. A disc 98a is shown on the collar 8|. The pyramidal shaped support is again indicated at I05 with its rod I Ill. The material carrier is again shown at 51;. The cap for the carrier is again shown at II 2a. The textile is shown at I220. 20 In this modif cation the heated air is forced through the textile I220 directly into the atmosphere.

It will be noted that with the present invention the suction side of a blower is employed to extract 25 water from a wet textile and that the discharge side of said blower is used to force heated air through the textile that has had its water previously extracted. Heretofore a blower was employed for extracting the water from the textile and a second blower was employed to blow the heated air therethrough.

Various modifications may be made in the invention and the present exemplification is to be taken as illustrative and not limitative thereof.
